Description

Microbubble generator

The present invention relates to a microbubble generator, and more particularly to a microbubble generator installed on a water outlet device and capable of increasing the gas content and bubble fineness of the water stream.

The conventional aerator is mainly composed of a pump, an outlet pipe connecting the pump, and a gas-liquid mixing pipe connecting the outlet pipe. The outlet pipe diameter is gradually tapered from the pump to the gas-liquid mixing pipe. The gas-liquid mixing pipe comprises a pipe connecting the outlet pipe and an air inlet pipe connecting the outside air, and the pipe has a larger diameter than the outlet pipe. When the pump draws the water out and pressurizes it to the junction of the outlet pipe and the conduit, the water flow will form a negative pressure after entering the conduit, and the negative pressure will cause the outside air to be sucked into the gas-liquid mixing pipe from the intake pipe, and The water flow is mixed into a bubble, and after the mixed bubble water flow is guided to the object to be washed, the purpose of rinsing and sterilizing through the aeration water can be achieved. If used to rinse vegetables, clean water with high gas content also has the effect of decomposing pesticides.

However, when the water flow of the conventional aerator structure flows through the gas-liquid mixing tube, the bubble volume is determined by the volume of the intake pipe and the water pressure of the pump. In addition, the pump water pressure must maintain the water flow to a specific flow rate above which the air can be drawn in. Therefore, if the user can lift the gas before the flow rate can be arbitrarily reduced, the average volume of bubbles generated in the gas-liquid mixing tube cannot be changed. If the user needs finer bubbles for water purification, the conventional aerator cannot meet the demand. . In addition, the liquid-gas mixture produced by the bubble mixing device has a gas content that is too low, and the bubble volume is not sufficiently small, and it is impossible to produce a water-gas mixture containing a large amount of dense bubbles and a color of milky white. Therefore, how to improve the lack of the aforementioned prior art is an issue that the industry is eager to overcome.

The purpose of this creation is to improve the problem of insufficient gas content in the mixing of liquid and gas in the conventional aeration device, and the bubble volume is not sufficiently small.

The surface constituting the ordered step arrangement is within the scope of the "complex step 611" of the present creation. When the water flows through the effluent conduit 60 through the water outlet member 20a, each of the vortex passages 62 formed by the blade 61 causes an acceleration effect of the water flow, and an impact force generated after the water flow collides with each of the step faces 611. The gas-containing components in the water are split again into smaller bubbles. With the above structure, the present invention can make the water flow sent by the water discharge device 900 contain a large number of fine bubbles, and can further improve the washing ability of the water.
